Lesson: Boyle's Law High School PhysicsPhysics
In this lesson, we will learn how to use the formula PV = constant (Boyle's Law) to calculate the pressure or volume of a gas that is allowed to expand or contract at a constant temperature.

A bike tire is pumped up using a foot pump. The pressure of the gas within the tire increases, but the volume remains the same. What happens to the temperature of the gas?
A sphere of gas expands from a radius of 0.5 m to a radius of 2 m. The temperature remains constant throughout. How many times smaller is the pressure of the gas in the sphere after its expansion?
At sea level on Earth, the atmospheric air pressure is about 101 kPa. At the top of Mount Everest, the air pressure is about 34 kPa. A balloon with a fixed amount of helium gas is taken from sea level up to the top of Mount Everest. The temperature of the air is the same at both locations. What happens to the size of the balloon?
